SAM without steam client

[henrydatei]

I'm just asking how SAM works. I'm terrible in reading code so I just want to know SAM works and if there is an opportunity to unlock achievements in an easier way, e.g. making an API call or something via Python etc.

There might be a web API at this point but SAM would have predated any web APIs that Valve made available.

SAM uses the Steamworks API.

Hm interesting, I analyzed the traffic of my whole computer when I used SAM but I have not found any request that looks like it has anything to do with achievements. Maybe I missed it.

[gibbed]

Any network activity wouldn't come from SAM, it would be via the Steam client.

[henrydatei]

That's why I monitored the network traffic of my whole computer

[gibbed]

I was clarifying in case you were filtering specifically for SAM.

Steam's network protocol is encrypted, so it wouldn't be obvious plaintext.

[henrydatei]

I know that nearly all network traffic is encrypted and so I installed a root certificate to decrypt everything

[gibbed]

Steam uses multiple protocols, the main one is not HTTPS and is custom.

[gibbed]

I'd recommend taking a look at SteamKit. I don't have much direct experience with Steam's network protocols as I've never had a need to dig into it in that depth.

Ok, that seems to be the explanation why I haven't seen any achievement related traffic. But that means that it will be hard to make the achivement-unlocking-process without the steam client.

我能否问一下 steam挂时长 是如何实现的 请求了哪个api呢 对此 我可以付费 Can I ask how the steam hang time is implemented and which API is the request that I can pay for
